KeyPRINT® KeySplint Hard™ is a biocompatible light-curing resin for high-strength rigid dental Splints and night guards. It provides therapy for severe bruxism and cases requiring tooth immobilization, with finer detail and thinner segments than soft materials — yet it is less brittle and slightly more flexible than other leading hard Splints, so finished devices are durable, easy to clean, abrasion- and stain-resistant, and easy to polish.
